4-Hydroxymethylpyridine → HCID 59013880, compound

Participants

Reaction Steps

2-Chloro-3-pyridinol (500 mg, 3.86 mmol) was dissolved in 20 mL of tetrahydrofuran along with 4-pyridyl methanol (465 mg, 4.26 mmol) and triphenylphosphine (1.15 g, 4.38 mmol). To this solution was added diisopropylazodicarboxylate (840 μL, 4.27 mmol). The reaction was stirred at room temperature overnight under a nitrogen atmosphere. The solvent was removed under vacuum and the residue was dissolved in 50 mL of ethyl acetate. The reaction mixture was washed 4 times with 25 mL portions of water. Then, the product was extracted by washing 3 times with 25 mL portions of 0.5 M HCl. The acidic washes were neutralized with 1.0 M NaOH and the product was extracted back into ethyl acetate with 3 washes of 25 mL. The combined organic fractions were dried with magnesium sulfate and concentrated under vacuum to give 620 mg of 2-chloro-3-(pyridin-4-ylmethoxy)pyridine as a yellow solid.
